  if(curl) {
    /* create a mime handle */
    mime = curl_mime_init(curl);
    /* add a part */
    part = curl_mime_addpart(mime);
    /* continue and set name + data to the part */
    curl_mime_data(part, "This is the field data", CURL_ZERO_TERMINATED);
    curl_mime_name(part, "data");
  }
}
```
